Some avian alarm calls are produced only by males, and call rate corresponds closely with recent mating success. This relationship might reflect protection of descendant kin. Such ostentatious risk-taking might also be sexy. We will manipulate male reproductive success in natural social groups to measure the effect on production of costly calls. Parallel lab experiments will selectively change alarm call rate to test whether this influences attractiveness to females. Results will test a controversial hypothesis, extend current models of parental investment and female mate choice, and permit a synthesis of work on sexual selection and animal cognition.

一些鸟类报警电话只由男性，和呼叫率密切对应最近的交配成功。 这种关系可能反映了对后代亲属的保护。 这种炫耀性的冒险行为可能也很性感。 我们将操纵自然社会群体中的雄性繁殖成功率，以衡量对昂贵呼叫产生的影响。 平行实验室实验将有选择地改变报警呼叫率，以测试这是否会影响对女性的吸引力。 结果将测试一个有争议的假设，扩展目前的模式，父母的投资和女性的择偶，并允许性选择和动物认知的综合工作。
